Supports dynamic expansion of the number of objects when extracting structured data

Is your feature request related to a problem? Please describe. When I extract the required structured object information from a large text, the number of objects is uncertain, and the number of objects cannot be dynamically expanded.

Describe the solution you'd like I hope to provide a way to dynamically expand the number of objects

Describe alternatives you've considered My current solution is to find the maximum number in the document and add object elements one by one in the code according to the maximum number. This is a very stupid method. When the maximum number exceeds 100 or even 1000, it is very difficult to handle.

(Note: The assist came from Luka Modrić.)\nAt the 28th minute, Liverpool's Mohamed Salah managed to wriggle free in the penalty area, got on the end of a floated cross from Trent Alexander-Arnold, but his header was saved brilliantly by Thibaut Courtois, denying Liverpool an equalizer.\nIn the 64th minute, Liverpool's Sadio Mané cut in from the right side, unleashed a powerful shot that rattled the crossbar, coming agonizingly close to leveling the scores.\nHowever, in the 69th minute, Federico Valverde of Real Madrid picked up the ball in midfield, drove forward with great pace, and unleashed a long-range shot that took a slight deflection off a Liverpool defender, wrong-footing Alisson Becker and doubling Real Madrid's lead to 2 - 0.\nIn the 80th minute, Liverpool made a desperate push for a goal. Diogo Jota came on as a substitute and almost immediately had an impact, getting a good chance inside the box, but his shot was blocked by the resolute Real Madrid defense.\nReal Madrid held on firmly in the closing minutes, and with their solid defensive display and clinical finishing upfront, they won the match 2 - 0, lifting the UEFA Champions League trophy."
